After [experimenting a little with vtkCaptionActor2D directly](https://discourse.vtk.org/t/vtkcaptionactor2d-and-the-size-of-leader-glyph/13721), I now switched to vtkCaptionWidget and like it a little better, with its automated arrow glyph and positionable text.
One thing I can’t figure out though is how to make the caption text **not scale** (or at least not so much) with the size of the window it is placed in (context: I use a 3D scene in a Qt widget, which is embedded in a larger layout and can be resized arbitrarily to better adapt to the user’s task at hand,.
With the `vtkCaptionActor2D` alone, I could achieve this by setting the `TextScaleMode` to `None`:
```auto
vtkNew actor2D;
actor2D->GetTextActor()->SetTextScaleModeToNone();
```
Trying the same on the `vtkCaptionWidget` seems to have no effect however:
```auto
vtkNew captionRep;
// captionRep setup...
captionRep->GetCaptionActor2D()->SetTextScaleModeToNone();
vtkNew caption3D;
// caption3D setup...
caption3D->SetRepresentation(captionRep);
```
The only way I found so far to affect the font size (but only relative to the automatic scaling) is via `vtkCaptionRepresentation`’s font factor:
```auto
captionRep->SetFontFactor(0.6);
```
There is probably some easy way to disable the automatic scaling in `vtkCaptionWidget` that I am overlooking?

Similar to [my other question](https://discourse.vtk.org/t/vtkcaptionactor2d-and-the-size-of-leader-glyph/13721/2), haven’t found an answer here yet and would be glad if anybody who has worked already a little with vtk’s text annotations could chime in…
